本标准规定了再生涤纶短纤维的产品分类、技术要求、试验方法、检验规则和标志、包装、运输、贮存的要求。
本标准适用于以回收的聚酯(PET)为原料经熔融纺丝生产的，线密度为0.8dtex～6.7dtex纱用再生涤纶短纤维、线密度为0.8dtex～22.2dtex非织造用再生涤纶短纤维及线密度为0.8dtex～33.3dtex充填用再生涤纶短纤维。线密度不在上述范围内的再生涤纶短纤维可参照使用。其它类型的再生涤纶短纤维亦可参照使用。

Scope

This standard specifies the terms and definitions, classification and labeling, technical requirements, test methods, inspection rules and marking, packaging, transportation and storage requirements for recycled polyester staple fiber. This standard applies to recycled polyester staple fiber for yarns with a linear density of 0.8 dtex ~ 6.7 dtex produced by melt spinning from recycled polyester (PET), and recycled polyester staple fiber for non-woven fabrics with a linear density of 0.8 dtex ~ 22.2 dtex. The fiber and linear density are 0.8 dtex~33.3 dtex. The recycled polyester short fiber is used for filling. Regenerated polyester staple fibers whose linear density is not within the above range can be used as a reference. Other types of recycled polyester staple fibers can also be used as reference.
